Embodiment Construction

[0038]FIG. 1 is a cross-sectional view of a unit discharge cell.

[0039] Referring to FIG. 1, a sustain electrode 12 including an X electrode 13 and a Y electrode 14 is formed on a lower surface of a first substrate 11 arranged at an upper portion of a discharge cell 10. The X electrode 13 and the Y electrode 14 respectively function as a common electrode and a scan electrode, and are separated from each other by a discharge gap. The X electrode 13 and the Y electrode 14 respectively include transparent electrodes 13a and 14a and bus electrodes 13b and 14b formed on lower surfaces of the transparent electrodes 13a and 14a. The sustain electrode 12 is covered by a first dielectric layer 15, and a protective layer 16 is formed on a lower surface of the first dielectric layer 15.

[0040] In addition, a second substrate 21 is disposed to face the first substrate 11, and an address electrode 22 is formed on an upper surface of the second substrate 21. The address electrode 22 is covered by...

Abstract

A Plasma Display Panel (PDP) includes: a first substrate including a plurality pairs of sustain electrodes, each of which includes an X electrode and a Y electrode separated from each other by a discharge gap, formed on a lower side thereof, and a first dielectric layer covering the pairs of sustain electrodes; a second substrate facing the first substrate and including address electrodes formed on an upper side thereof to cross the pairs of sustain electrodes, and a second dielectric layer covering the address electrodes; and a barrier rib including first barrier ribs formed on the second dielectric layer to interpose at least one address electrode therebetween, and second barrier ribs crossing the first barrier ribs to define discharge cells, in which a phosphor layer is formed. Each X electrode and each Y electrode respectively include bus electrodes, and transparent electrodes having protrusions, which are spaced apart from the second barrier ribs and corresponding to the discharge cells, and extension units extending from the protrusions and connected to the bus electrodes.

Description

CLAIM OF PRIORITY [0001] This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for PLASMA DISPLAY PANEL earlier filed in the Korean Intellectual Property Office on 18 Feb. 2004 and there duly assigned Serial No. 2004-10671. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a Plasma Display Panel (PDP), and more particularly, to a PDP having an improved discharge efficiency resulting from the prevention of mis-discharges and the ensuring of an address voltage margin. [0004] 2. Description of the Related Art [0005] In general, in a PDP, a glow discharge is generated by supplying a predetermined voltage to electrodes, the electrodes having a gas filled sealed space therebetween. A phosphor layer formed in a predetermined pattern is then excited by ultraviolet rays generated by the glow discharge to display an image. [0006] PDPs can be classified as D...
